HYDRAULIC PUMP.

Application filed June 26,

To all whom it may concern Be it known that I. J AMES G. Haarrron, a citizen of the United Statesresiding at Lafontaine, in the county of Wilson and tate oi Kansas. have invented certain new and useful improvements in Hydraulic Pumps, of which the following is a specification.

This invention has reference to hydraulic pumps whereby the weight of a column of water in a storage tank and acting upon a reciprocatory piston serves to actuate anoth r piston ofsmaller area than the first named piston to draw water from the storage tank and force it to a higher level, whereby the actuated water may be utilized in a house and the waste water may be utilized for stock or the like.

The invention will be best understood from a consideration of the following detailed description-taken in connection with the accompanying drawings, forming part of this specification. with the understandin however that the invention is not confine to any strict conformity with the showing of the drawings, but may be changed and modified so long as such changes and modifications mark no 'material departure from' the salient features of the invention as expressed in the appended claims.

In the drawing there is shown a pump structure partially in elevation and partially in section. whereby water from an elevated tank or receptacle is utilized to actuate a pump structure by gravity to raise the water to a higher elevation or to put air under compression. as the case may be.

Referring to the drawings. there is shown a cistern or reservoir 1 for. containing a. supply of water to be utilized.

lVithin this reservoir is a strainer or filter whereby the water to be used may be maintained in a pure condition.

Dropping from the tank 1 is a pipe 3 with the extent of drop being determined by conditions.

At a suitable distance below the tank 1, the pipe 3 terminates in a branch pipe 4: in turn leading into a low portion of a cylinder 5 and within the cylinder 5 is a piston 6.

Above and supported by legs 5 rising from the cylinder 5 there is located another cylinder 7 having within it a reciprocatory piston 8 connected to the piston 6 by a piston rod. 9 and leading from the top of the cyli-n 1922v Serial No. 570,920.

' 'der 7 is a pipe 10', which may extend to a house or other point of utilization of water forced through the pipe 10. I V

The piston 8 is provided with a through passage 11 controlled by a valve 12preferably urged toward a closed position by a spring 13,'such as shown in the drawing,

or of any other appropriate shape.

The pipe 10 is provided with a oneway check valve 14, while the pipe 4 has included in it a three-way valve 15 controlled byan over-balanced bell crank handle 16 to Which is attached a link 17 secured to one end of a rock lever 18 mounted on the cover portion of the cylinder 5.

Projectingfrom the piston rod are l spaced' adjustable'stops 19, 20'capable of moving into and out of the-interior of the cylinder 5 through a passage 21 in the head of the cylinder 5; which head is'indicated Leading from the pipe 3 is a bend or siphon portion 3 and a pipe 23 containing a cut-off valve 24:. which valve may for convenience be a globe valve, and also contain ing a check valve 25.

Leading from the valvev 15 isa pipe 26 to dispose of waste water from the cylinder 5 beneath the piston 6.

With an apparatus such as shownand described, water from the tank 2 may be placed under superior pressure depending upon the diii'erence in size of the pistons 6 and 8, these pistons having the same stroke, but the piston 6 being relatively large as compared with piston '8. V i

:r from the tank 1 to gravitate into the cylinder 7, the weight of such water bearing upon the upper surface of the piston 8,

1 the piston rod 9 upon the piston 6 in the cylinder 5. the valve 15 at the time opening to permit the escape of any water which may be in the cylinder 5 against the under face or" the piston 6. V

When the stop 19 reaches the rock lever 18, l the arm .16 is raised toaposition permitting By opening the valve 2 k and allowing its overbalanced end to snap over causing the emptying of the cylinder When the piston 6 has raised to the full extent the stop 30 engages the lever 18 the flow of Water into the cylinder has lifted the piston 6 sufiicient to cut off the flow of Water from the tank 1 into the cylinder 5, such flow raising the piston 8 in the cylinder '7, and forcing Water or air, as the case may be, above the piston 8 into. the pipe 10 to the point of utilization.

lVhat is claimed is 1. A hydraulic pun'ip comprising, a pair of spaced vertically positioned aligned piston chaii'ibers, the upper of less capacity than the lower, a piston head in each chamber, the head in said upper ehan'iber having a passage therethro'ugh, a piston rod connecting said heads, a liquid supply pipe connected to each chamber, a lead-off pipe in said upper chamber, said supply and leadoif pipe enteringvsaid upper chamber above the: piston head, a .three \va valve and supply pipe leading to the lower chan'iber, a drain-0ft pipe from said valve, said supply pipe'entering the lower chamber below the pi ton head, a spring pressed flap valve upon the top of said upperpiston head, and normally closing the passage therethrough, spaced stops upon said piston rod, and pivoted means connected with said three vvay valve and intermittently operating said valve through the action of said stops.

2. A hydraulic pump comprising, a pair oi spaced vertically positioned aligned piston chambers, the upper of less capacity than the lower, a piston head in each chamber, the head in said upper. chamber having a passage thcrethrough, a piston rod connecting said heads, a liquid supply pipe con nected to each chamber. leadpfi pipes in said upper chamber. said supply and leadoii pipes entering said upper chamber above the piston headga three Way valve and suppl pipe leading to the lower chamber, a drain-off pipe from pipe entering the lower chamber below the piston head, a spring pressed fiap valve upon the top of said upper piston head, and normally closing the passage therethrough, an over-balanced bell crank lever controlling said three Way valve, a rock lever mounted upon said lower chamber, and a link connection between said lever and one arui'ot said bell crank lever, the other end 0'5 said id valve, said supply
